Exact and practical pattern matching for quantum circuit optimization

11 Sep 2019Qiskit/qiskit-terra

An important building block for many quantum circuit optimization techniques is pattern matching, where given a large and a small quantum circuit, we are interested in finding all maximal matches of the small circuit, called pattern, in the large circuit, considering pairwise commutation of quantum gates.

TensorNetwork on TensorFlow: Entanglement Renormalization for quantum critical lattice models

28 Jun 2019google/TensorNetwork

We use the MERA to approximate the ground state wave function of the infinite, one-dimensional transverse field Ising model at criticality, and extract conformal data from the optimized ansatz.

A quantum-classical cloud platform optimized for variational hybrid algorithms

13 Jan 2020rigetti/pyquil

In order to support near-term applications of quantum computing, a new compute paradigm has emerged--the quantum-classical cloud--in which quantum computers (QPUs) work in tandem with classical computers (CPUs) via a shared cloud infrastructure.

Visualizing and Interpreting Unsupervised Solar Wind Classifications

28 Apr 2020JustGlowing/minisom

The manual and semi-automatic classification of millions of hours of solar wind data from multiple missions can be replaced by automatic algorithms that can discover, in mountains of multi-dimensional data, the real differences in the solar wind properties.
